About Ryan G Thomas
About the Provider
Like many members of my family, I grew up with asthma. I know firsthand how hard it can be to deal with breathing difficulties. So I decided to become a pulmonologist, and during my medical residency I discovered just how much I enjoyed working with kids. Pediatric pulmonology really is the perfect fit for me. I’m especially passionate about treating asthma, cystic fibrosis, and croup. I also teach medical students, residents and fellows as part of my career. I try to utilize the skills I’ve learned from teaching to help patients and families better understand their child's illness and the treatment options available.
In my practice, I try to give parents choices whenever possible. I take time to explain the strengths and weaknesses of each treatment approach so that parents can make informed decisions about what will be best for their child.
I strive to empower families with tools they need to manage their child’s condition successfully at home. It’s truly a wonderful feeling when I can help keep a child out of the hospital, or see the relief on a parent’s face when they learn how much they can do to keep their child healthy and safe.

We cannot say enough wonderful things about Dr.Thomas! We left our visit feeling relieved and all our questions were answered. We felt heard and Dr. Thomas explained things to us in a way we were looking for/didn’t receive elsewhere.

Listen to both of us and explained things very well. Wanted to make sure we were comfortable with diagnosis and understood what it meant
